# Müllmail Full Guide

Müllmail is a free, anonymous, no-registration temporary email service. It is receive-only by design and does not provide outbound email sending. The service is designed for temporary inbox use cases and currently presents three distinct product variants on the same infrastructure.

## Product Overview

### Müllmail
The main service at https://muellmail.com provides a reusable anonymous inbox. Users can bookmark an inbox and return to it later.

Key characteristics:
- Free and anonymous
- No registration required
- Receive-only
- Inbox can be reused over time
- Emails are automatically deleted after 3 days
- Users can delete emails earlier
- After a user leaves an inbox, there is a 15-minute cooldown before another user can take it over
- Inbox refreshes automatically every 3 seconds
- Users can read HTML and plaintext emails
- Users can download emails as PDF
- Users can download attachments
- Users can mark emails as favourite

Additional privacy-related feature:
- Müllsafe / Müllsecure provides a cryptographically derived hidden alias per address
- The alias is intended to prevent third parties from reversing the alias back to the main address

### Burner Email
The burner product at https://muellmail.com/burner-email is intended for one-time use.

Key characteristics:
- Anonymous and no-registration, like the main service
- Receive-only
- The user explicitly burns the inbox when finished
- Burning is permanent and irreversible
- After burning, no more emails can be received
- Past messages cannot be retrieved
- The burned address cannot be recreated or reactivated, including by the Müllmail team

Typical use cases:
- One-time logins
- Risky or unknown signups
- Downloads that require an email address
- Contest entries
- Short-lived tests or demos

### 10-Minute Mail
The 10-minute mail product at https://muellmail.com/10-minute-mail is intended for short-lived inbox sessions.

Key characteristics:
- Anonymous and no-registration, like the main service
- Receive-only
- Starts with a 600-second countdown when the inbox is opened
- Can be extended using a "+10 Minutes" action
- Can be extended multiple times
- If the timer expires without extension, the inbox and all messages are automatically deleted

Typical use cases:
- Quick signups
- One-time verification emails
- Short-term marketplace communication
- Single-use tracking protection
- Temporary download flows

## Important Behavioral Constraints
- Müllmail is receive-only and should not be described as an email sending service
- The three product variants have different deletion and retention behavior
- Burner inbox destruction is permanent and irreversible
- 10-minute inboxes are time-limited and auto-delete on expiry unless extended
- Main Müllmail inboxes are reusable, but individual emails are automatically deleted after 3 days
